Hm... are you saying that the dropdown is showing extra space in addition to the width of the column?

The default behavior of the combo is to size the DropDown to the columns automatically. So if you are getting extra space it's because you changed something.Like maybe you are setting the DropDownWidth property on the Combo. That's not what you need in this case, though. What you should do, instead, is change the width of the Column in the dropdown and let the dropdown itself size to the column - which it will do automatically unless you also changed the AutoSizeMode.

Hi,

Okay... so what are you trying to autosize the column to? AutoSize means setting the width of the column based on the contents so you make sure all of the text in the column is visible to the user with no scrollbars. Is that what you want?

Or are you trying to make the column in the dropdown (and thus the dropdown itself) the same width as the grid column it's in?

Also... may I ask why you are using an UltraCombo? There are easier ways to provide a list in a grid cell.

The UltraCombo shows ONE column as I want to display it as 'normal' drop down. This column should span the entire width of the UltraCombo, otherwise it looks strange (when selecting items, the selection is cropped at the column border). No matter what I do, I cant accomplish this.

So I am not trying to resize the main grid column, I am trying to resize the drop down grid column.

Any suggestions?
